# This may not be the best DLS soundfont to use with Doom, but it's
# only one of two freely-available ones I found on the web. The other
# is called "General MIDI DLS SoundFont", from CodeWeavers, and it's
# missing too many samples to be worth using.

# 20230625 bkw: get rid of unrar dependency, use bsdtar instead.
# not incrementing BUILD, since the package doesn't change.
